PATENT LIFE-PRESERVER.

SPECIFICATION forming part of Letters Patent N o. 724,279, dated March31, 1903. Application filed March 25, 1902. Serial No. 99,879. (Nomodel.)

ToftZZ 7,077,071?, it may concern:

Be it known that I, BENJAMIN GoLDsTEIN, a citizen of the United States,residingin Atlantic City, in the county of Atlantic, State of NewJersey, have invented new and useful Improvements in Life-Preservers, ofwhich the following is a specification.

My invention consists ofa life-preserver having a belt or chamber whichmay be iniated by gas created as required.

Figure l represents a perspective view of alife-preserverembodyingmyinvention. Fig. 2 represents alongitudinalhorizontal section thereof. Fig. 3 represents a view of a detachedportion. Fig. 4 represents a view of a modification.

Similar letters of reference indicate corre' sponding parts in thefigures.

Referring to the drawings, A designates aA belt which is hollow andinflatable. B designates a gas-generator which is connected with saidbelt and is in communication there-V with by means of the stud or nippleC, said generator consisting of the chambers or holders D and E, whichare separated b v the partition F, so as to be primarily placed out ofcommunication.

G designates the head or cap of the chamber D, the same being "connectedwith the body of said chamber D by the elastic connection H, wherebymotion may be imparted to said head in the direction to and from thepartition F. The space between said cap and said body7 is closed underall circumstances by said elastic or liexible connection, thuspreventing the entrance of water to said body.

Within the said chamber D is the pin J, which" is secured at one end tothe cap or head G and having its other end pointed and placed adjacentto the partition F.` On thenipple C is the diaphragm K, made of suchmaterial as to fuse or be loosened by the action of the gas that may begenerated in the member B,

said diaphragm primarily closing the comm unication between thelgenerator and belt.

A'The operation is as follows: Asuitable gasproducing material, such ascalcium carbid, is placed inthe chamber E and water in the chamber D.When service of the preserver is required, the head or cap G is pushedin,

5 whereby the point of the pin J pierces the in communication. As thewater now enters the chamber E and acts upon the carbid, gas

.is generated, which, beingy hot in its nature,

partition F, thus placing the chambers D E the nipple C the hook and eyeL, itbeing evident that when the latter-named parts are disconnected thegenerator may beunscrewed from the nipple C, and thus removed.

In order to adapt thebelt to the waists of wearers of increased sizes,portions of 'said belt are folded or made overlapping, as at M, so thatthe belt may be distended or enlarged. In order to cause the belt tocontract on the waist of the wearer, there is secured to the belt atplaces about the overlapping portions M the piecesV N of elasticmaterial, which while yielding create the necessary pressure to causethe belt to remain in position.

In order to prevent any possible slipping or dropping of the belt fromits position, hooks P may be attached to the same for engagement withthe garment of the wearer.

In lieu of the belt A receiving the gas a chamber A' may be connectedwith the belt A2 or with the generator B, so as to be inlated from thelatter and form a float for a purpose similar to said belt A wheninflated.

Various changes may be made in the details of construction withoutdeparting from the general spirit of my invention, and I do not,therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is l l. In a life-preserver, a gas-generatorconsisting of ohambers,a closed partition between the same, a movablehead on one of said chambers, a water-tight liexible connection for saidhead and chamber, and an instrument adapted to open said partition, thesame being attached to said head and extending in the adjacent chambertoward saidpartition.

2. A life-preserver consisting of a gas-gen- ICO erator, formed of aplurality of chambers, a closed partition between said chambers, a headon one ot' said chambers, and a dischargeopening on the other chamber, afusible diaphragm around said opening, a movable head on one of saidchambers, a piercing implenient within said chamber connected With saidhead, and a Water-tight connection for said head with said chamber.

3. In a life-preserver, a generator for gas adapted to inate a chamberof the preserver, consisting of holders for materials of gas-producingnature, a partition primarily separating said holders, a device foropening said partition, a head carrying said device and a Water-tightmovable connection for said bead with the adjacent holder.

4. In alife-preserver, a chamber adapted to be inflated, and a generatorfor gas connected with the same, consisting of holders, a closedpartition separating the same, a movable head on one holder, awater-tight flexible head connecting said head with said holder and animplement attached to said head adapted to pierce or break saidpartition.
